Application led June 14, 1924. Serial No. 719,922;

This invention aims to provide an 1mproved separablefastener. l

In the drawings, which illustrate a preferred embodiment of my invention Figure 1 is a front elevation of a preferred form of fastener;

Fig. 2 is a front elevation of the socket as attached to a support;

Fig. 3 is a section on the line 3 3 of Fig. 1, being partly in elevation; Fig. et is a section on the line 1l-'1 of 1, showing the stud in unlocked position prior to disengagement from the socket;

Fig. is a real' elevation of the stud; Fig. is a section on the line (5-6 oi: Fig. el 5 yand Fig. 7 a section on the line 7 7 ot Fig. 4l. y Y

`Referring to the preferred form of my invention', fl have shown a stud attached to a curtain 1 and a socket attached to the body of an automobile. I The preferred form of stud is provided with a socket-engaging part 3 having longitudinal slits 4 to permit contraction and expansion of the head when engaging and li engaging a socket. The socket-engaging part 3 is preferably pressed from the back plate 5 and is secured to that side of the curtain adjacent the socket'by means of prongs 6 struck up from the peripheryof an attaching plate 7. These prongs pierce the curtain andV are thereafter curled outwardly andr downwardly by an anvil portion 8 integral with a front plate at the opposite sides of the curtain 1.

The attachingr plate 7 also presents a tubular part 7 which surrounds the socket-engaging part 3 throughout a portion of its length to provide a supportl therefor.

A press-button 9 is located within the socket-engaging part 3 and held `therein by prongs lO thrown inwardly from the back plate 5. When the stud is assembled to the curtain 1, the press-button vr9 is concealea'l from view by the curtain and is operatedr by pressing upon that part of the curtain which is exposed through an laperture 11 provided in the front plate. intact when the stud is attached thereto, thereby reducingto a minimum vthe possibility of tearing away from the stud.

The preferred form of socket is attached to the body Q. Yof an automobileA by means of a screw 12 which is provided'-V with a split flin- Thus the curtain is left' tongue 13 generally rectangular in crosssection and adapted to pass through an aperture of the same cross-sectional dimensions located at the inner end le of the socket ing 15. The split tongue is thereafter flattened against the inner surface of .the end let of the casing, as best illustrated in Figs. 3, Lland 7. lVhe'n the screw is thus attached to the socket, there canbe no relative movement of one part without a like movement of the other. The lcasing 15 presents at its outer end a flange 16 having a hexagonal periphery over which is clenched a portion ofl :1 front plate 17 thereby toA secure the two parts together in a fixed relation to each other. The hexagonal periphery of the front plate provides a means for reception of a socket wrench or the like to attach the socket to the body of the car, there being a recess therein'so that the casing .15 will be countersunk into the body of the car, as best illustrated in Figs. 3 and e. The front plate 17v presents a stud-receiving aperture 13 therethrough, `normally closed by a hatshapedlocking disc 19 urged into apertureclosing position by a'spring 20.

The stud may he engaged with the socket by pressing uponv the anvil part of the frontplate, thereby forcing the socket-engaging part 3, of the stud,into the stud-receiving 4aperturevlS. The head of the stud contracts as it enters the aperture and also engages the locking disc and urges it inwardly against the pressure of the spring 20, until the head expands, thereby permitting the crown part of the locking 'disc to enterv therein and engage the reversely bent portions 21 of the stud, thereby to preventcontraction of the head of the stud.

plate. Thus the press-button is urged in wardly and forcesV the crown partl of the locking disc outof engagement with the reversely bent port-ions Qlfof the stud thereby permitting' contraction and withdrawal Thusthe stud is locked lwith the socket and cannot be separated lli) thereof from the stud-receiving aperture, as best illustrated 1n Fig. 4l. l j

`While l have shown and described a preferred form of one embodiment of my invention, it will be understood that changes 'involving omission, substitution, alteration and reversal of parts, and even changes lin the mode of operation, may be made without departing from the scope'of my invention, which is best defined in the following, claims.

claiml. A separable fastener comprising, in combination, a socket presenting a stud- Vreceiving aperture, a stud including a socketengaging member for engagement with said aperture, means for securing said socketengaging member to a. stud-carrying medium, locking means forming part of the fastener assembly for locking said stud and socket together and press-button means located between the stud-carrying medium and the locking means, said `press-button means operable by pressure exerted upon the stud-carrying medium adjacent said press-,button means for shifting said locking as said socket-engaging member and operable by pressure exerted upon the studcarrying medium adjacent said press-button means for shifting said spring-pressed locking part located in saidsocket into unlocking position. f

31A separable fastener comprising,l in combination, a socket presenting a stud-receiving aperture, a cooperating stud having a headfor engagement with said aperture, spring-pressen locking means located in said socket for locking said stud and socket together and a concealed press-button assembled with said j, stud and located entirely 'be ond the inner face of a stud su) ort said press button operable pressing upon the Vouter face ofthe stud support to move said locking means into unlocked position thereby to permitV separation of said stud lfrom said socket.

j il. A separable fastener comprising, in combination, a socket presenting a stud-receiving aperture, a cooperating stud secured to a flexible carrying medium and having a head contractible and leXpansible for engagement with said aperture, spring-pressed locking means for locking said stud and socket together and a concealed press-button located between said locking means'and the flexible carrying medium and manually operable to move said locking means into unlocked position thereby to permit separation of said stud from said socket, V said spring-pressed locking `means and pressbutton forming part of the fastener assembly.
